CRANK- CONNECTOR.

SPECIFICATION forming part of Letters Patent No. 789,344, dated May 9,1905. Application filed January 23, 1905. Serial No. 242,283.

To all whom it may concern.-

Be it known that 1, WILLIAM VVATTIE, a citizen of the United States,residing at VVorcester. in the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements inOranklonnectors for Looms, &c., of which the following is aspecification.

My invention relates to improvements in connectors, and moreparticularly to improvements in crank-connectors for looms which connectthe crank-shaft with the lay.

In the ordinary construction of crank-connectors the connector is oflixed length, and in case of any desired variation in the extremepositions of the lay in its movement there is no provision for adjustingthe length of the connector.

The object of my invention is to provide an improved connector thelength of which may be adjusted or varied as desired.

My invention consists in certain novel fea tures of construction of myimprovements, as will be hereinafter fully described.

Referring to the drawings, Figure 1 is a side view of a crank-connectorembodying my improvements. Fig. 2 is an edge view of the connector shownin Fig. 1 looking in the direction of arrow a. Fig. 3 is a longitudinalsection on line 3 3, Fig. 1, looking in the direction of arrow a, samefigure; and Fig. 4

shows the adjusting-screw detached.

In the accompanying drawings the connector 1 is made in two parts 1and 1. The end of the part 1 is recessed or concaved to receive a crank(not shown) and has secured thereto the strap 2, which in this instanceis adjustably secured to the connector by a bolt 3, which extendsthrough a block 4:, located within a recess 5 in the end of theconnector (see Fig. 3) and has a nut 3 thereon.

The block 4 within the recess 5 is supported on and held in position bya screw 6, having a screw-threaded inner end 6, which turns in ascrew-threaded hole in said block 41, and an enlarged head 6, whichextends within an opening 7 through the part 1 of the connector 1 andbears against the end of said opening. By turning the adjustingscrew 6in or out the block 4 is moved, and with it the strap 2, to increase ordiminish the size of the opening formed by the strap 2 and the curvedend on the part 1 of the connector 1. After the screw 6 has been turnedto adjust the strap 2 as desired a screw 8 is turned in to hold thescrew 6 in position.

The part 1 of the connector 1 at its inner end is adjustably attached tothe inner end of the part 1 of the connector 1 by two bolts 9, whichextend through elongated openings 10 in each of the parts 1 and 1 (seeFig. 1) and have nuts 9 thereon.

The part 1 of the connector 1 has on its outer end a hub 11 with anopening 11' therethrough for pivotal attachment to the lay or otherdevice. The inner end of the part 1 on its inner surface has a half-nutor screwthreaded recess 12 therein (see Fig. 3) to receive and engagethe enlarged screw-threaded end 13 on the adjusting-screw 13. Thescrew-threaded end 13 of the adjusting-screw 13 extends loosely within aplain recess 1st in the inner end of the part 1 of the connector 1.which is directly opposite and contiguous to the screw-threaded recess12 in the part 1. (See Fig. 3.) The length of the recess 14 correspondsto the length of the threaded end 13 of the adjusting-screw 13. Theouter end of the adjusting-screw 13 is preferably provided with a head13" with a hole 13" therein to receive a pin or other device for turningsaid adjusting-screw.

In order to adjust or vary the length of the connector 1, the nuts 9 onthe bolts 9 are turned off or loosened and the adjusting-screw 13 isturned in one direction or the other, according to whether the connector1 is to be made shorter or longer. The movement of the threaded end 13'in the threaded recess 12 on the part 1 of the connector 1 will move theparts 1 and 1 of the connector 1 in the direction of their length towardeach otheror away from each other, according to the direction ofrotation of the adjusting-screw13.

- After the two parts 1 and 1 of the connector lhave been adjusted asdesired relative to each other the nuts 9 on the bolts 9 are screwed upto secure the parts 1 and l of the connector 1 together and in theiradjusted position.

The advantages of my improvements will be readily appreciated by thoseskilled in the art.

It will be seen that by simply loosening the nuts 9 on the bolts 9 andturning the adjusting-screw 13 the length of the connector 1 may bevaried as desired within certain limits corresponding to the lengthot'the slots or openings in the inner ends of the parts 1 and 1 of theconnector 1. 4

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An adjustable connector, comprisingtwo parts, adjustable on eachother in the direction of their length, and one part having ascrewthreaded recess therein, and the other part having a plain recesstherein, said recesses directly opposite and contiguous to each other,an adjusting-screw, having an enlarged screwthreaded end which engageswith and turns in said threaded recess, and also turns loosely withinthe plain recess and is adapted to engage the ends thereof, and meansfor securing the parts together, substantially as shown and described.

2. An adjustable connector, comprisingtwo parts adjustable on each otherin the direction of their length, means for securing said partstogether, an adjusting-screw having a thread thereon which engages withand turns in a threaded recess in one of the parts, and also engageswith a recess in the other part, anda second adjusting-screw having athread thereon which engages witha movable block within one end of theconnector and said block, and a strap attached thereto, on the end ofthe connector, substantially as shown and described.

3. In a connector, the combination with the two parts of the connector,adjustable in the direction of their length, and one part having athreaded recess therein, and the other part a recess therein, of a screwhaving a thread thereon which engages with and turns in said threadedrecess, and also engages said other recess to adjust the two parts ofthe connector, and means for securing said two parts together, and ascrew having a thread thereon which engages with a movable block withinone end of the connector, and said block, and a strap attached theretoon the end of the connector, substantially as shown and described.
